[0001]
BACKGROUND OF THE INVENTION
  The present invention relates to a photographic processing apparatus such as a photographic printing development processing apparatus for developing an image on a photosensitive material by projection printing or adhesion printing.
[0002]
[Prior art]
  Conventionally, in the case of close-contact printing that obtains a composite image of a pattern and characters, in the case of a print with a border (with a border) as shown in FIG. The device is equipped with a photographic paper magazine containing a photographic paper reel in which photographic paper as a long photosensitive material is wound in a roll shape. From the photographic paper reel in this photographic paper magazine The supplied photographic paper P is conveyed to a printing processing unit. In this printing processing section, the printing paper is moved and outputted every one to several lines, and the digital image is printed on the printing paper in close contact printing. In this way, the image and characters printed on each area of the photographic paper are cut by the cutter, and the cut photographic paper is transported toward the development processing section, and the development processing section performs the development processing. I was doing.
[0003]
  Further, in the case of printing to obtain a composite image of a pattern and characters, and in the case of a borderless specification (borderless) print as shown in FIG. 10B, the photo processing apparatus is in the photographic paper magazine. The photographic paper P supplied from the photographic paper reel is cut to a predetermined length with a cutter, and the cut photographic paper P is conveyed to a printing processing unit. In this printing processing unit, the character area of the photographic paper P is covered with a shielding mask, the pattern is printed on the pattern area, the character area is covered with the shielding mask, and the character negative is applied to the character area of the photographic paper. I was trying to burn it. In this way, the photographic paper that has been cut and printed with images and characters on each area of the photographic paper is conveyed toward the development processing section, and the development processing section performs the development processing.
[0004]
  In addition to this, as a case of obtaining a print having no border (borderless) specification as shown in FIG. 10B, a specification with a border having a white border as shown in FIG. 10A (with border). It is also conceivable that, after the print is obtained as described above, four white edges are cut from the print by a cutter.
[0005]
[Problems to be solved by the invention]
  However, as shown in FIG. 10A, in the case of a print with a margin (with a border) as shown in FIG. 10A, a roll-shaped photographic paper is conveyed by a roller. The digital image to be output every one to several lines is printed on the photographic paper, and the print on which the digital image of the picture or character is printed is cut at the cutter position a of a predetermined length. In the case of print without border (borderless) specification as shown in FIG. 10B, it is not the projection printing as shown in FIG. When cutting photographic paper, the cut photographic paper must be sandwiched in order and transported to the close-contact printing unit, or the cut photographic paper must be sequentially sucked and transported to the close-contact printing unit using a vacuum suction device. Without contact The conveyance unit for the printing unit becomes complicated, and it is difficult to control conveyance because the conveyance accuracy of the photographic paper has to be precise in order to adhere and print a digital image every one to several lines on the photographic paper while moving the photographic paper. There was a problem that there was.
[0006]
  On the other hand, in the case of printing without a border (borderless) specification as shown in FIG. 10B by close-contact printing using roll-shaped printing paper, the printing paper is cut to a predetermined length on the downstream side of the printing processing section. Then, although the precision of the conveyance accuracy and the complicated conveyance configuration described above are solved, adjacent print end portions (end portions of the exposed portions) overlap each other, and simply cutting at the cutter position a3 at the center of the boundary. There was a problem that the overlapping part (exposed part) remained at both ends of the print and was unsightly. Therefore, the specifications for drawing out the photographic paper from the photographic paper reel in which the photographic paper is wound into a roll shape and sequentially printing the prints on the printed sheet to a predetermined length can only be printed with a border (with border). I couldn't handle it with borderless printing.
[0007]
  In addition, when cutting four white edges from a print with border (with border) to make a borderless (borderless) print, the cutter structure and its control are complicated and the size of the print itself is also large. It had the problem of becoming smaller.
[0008]
  The present invention solves the above-described conventional problems, and provides a photographic processing apparatus that can also cope with borderless (borderless) prints that are cut after the photographic paper has been subjected to the adhesive printing process in roll specifications. Objective.
[0009]
[Means for Solving the Problems]
  The photographic processing apparatus of the present invention is a photographic processing apparatus for printing an image on a photosensitive material supplied from a reel for photosensitive material to a printing processing section, and is provided on the downstream side of conveyance of the printing processing section. A cutter member for cutting the photoconductor material that has been subjected to printing, and at the time of printing with a margin specification, the cutter member and the photoconductor material conveying member are driven and controlled so as to cut the photoconductor material to a predetermined length, Cutter drive control means for driving and controlling the cutter member and the photosensitive material transport member so as to cut the photosensitive material to a predetermined length and further cut off unnecessary portions of the printed edge during printing without borders, and the cutter. A chip storage member disposed below the member and capable of storing an unnecessary portion of the print edge cut off by the cutter member; and provided downstream of the cutter member.Have a planeA first guide member;The guide plate is disposed below the first guide member and has a vertical flat plate portion. The guide plate is connected to the guide plate, and is formed on the upper edge that is bent at right angles to the flat plate portion. , Receiving photosensitive material A conveyance guide part composed of an upstream part constituting a receiving opening opened on the inlet side and a downstream part parallel to the first guide on the downstream side, and a rotation center for pivotally supporting the guide plate on the flat plate part By having a pin member asA conveyance guide position for opening a receiving port for the photosensitive material with respect to the first guide member;By making the upstream part parallel to the plane of the first guide member,Between the chip guide position that closes the receiving port and guides an unnecessary portion of the cut-off printed end into the chip storage member.Rotate around the pin memberfreelyWas madeWhen the unnecessary portion of the second guide member and the print edge is cut off, the second guide member is controlled to be positioned at a chip guide position, and when the photosensitive material is cut to a predetermined length, the second guide member is controlled. And a guide member drive control means for controlling the second guide member to be positioned at the transport guide position.
[0010]
  With this configuration, in the case of printing with a border, the printed photosensitive material is cut to a predetermined length with a cutter member, and in the case of printing without a border, the photosensitive material is cut to a predetermined length. In addition, since it is controlled to cut off the edge of the adjacent print that has been exposed excessively, the adjacent print edge (the edge of the exposed area) will not overlap and remain. It is not unsightly, and it is also possible to cope with borderless prints that are cut after sequential baking processing using a photosensitive material material reel in which the photosensitive material is wound in a roll shape.
[0011]
  Further, when the photosensitive material is cut to a predetermined length, the second guide member is positioned at the conveyance guide position, and when the unnecessary portion of the print end is cut off, the second guide member is positioned at the chip guide position. Therefore, the conveyance guide and guide guide can be shared, reducing the number of parts, and even if unnecessary parts of the print edge cut off by the cutter member are scattered during cutting, it is more securely stored in the chip storage member. As a result, it is also possible to eliminate the case where chips are scattered and clogged into the conveying system at the time of cutting.
[0012]

In particular, the cutter drive unit 473 is driven and controlled by the cutter drive control unit 474 described above, and the guide drive unit 478 is driven and controlled by the guide member drive control unit 479 described above.
[0050]
  The operation of the above configuration will be described below.
[0051]
  Next, when the second printing processing unit 4 is selected by the selection key, the photographic paper P drawn out from the photographic paper reel 33 in the magazine 3 is loaded onto the first conveyance path 43. .
[0052]
  The case where the second printing processing unit 4 is selected is a case where a composite image of a pattern image and a character image is required. In this case, as a previous step, a pattern image such as a film is read in advance by an imaging device by an external device such as a personal computer, and character data is input from a keyboard or the like and synthesized with the pattern image. Image processing is performed.
[0053]
  When the previous operation is completed, various conditions are set, and the start switch is turned on, it is first determined whether or not the leading edge cutting process of the photographic paper has been designated (step S1). This leading edge cutting process cuts the leading edge portion by a certain length (for example, about 100 mm) perpendicular to the longitudinal direction when the leading edge of the photographic paper in the magazine 3 is not cut perpendicular to the longitudinal direction. Refers to processing.
[0054]
  When this leading edge cutting process is not designated (NO in step S1: when the leading edge of the photographic paper is cut at right angles to the longitudinal direction), the first photographic paper drawn out from the magazine 3 is transferred to the first transport unit 43. Is loaded (step S2).
[0055]
  At this time, as shown in FIG. 3, the driven roller 438 is separated from the driving roller 439, and the loop guide 436 of the loop forming portion 435 is switched to the first position (solid line position). In this state, the conveyance roller 434 rotates and the printing paper P is pulled out from the magazine 3 until the leading edge of the printing paper P reaches the printing paper sensor S2.
[0056]
  The pressure pad 416 is moved to a position away from the display surface 414 of the image display unit 411, and prints the photographic paper P on which the guide plate 462 and the driven roller 465 of the stock unit 46 are conveyed from the upstream side. The paper storage box 461 has moved to a position where it can be guided.
[0057]
  Thus, when the leading edge of the photographic paper P reaches the photographic paper sensor S2, the loop forming unit 435 starts forming a loop of the photographic paper P, and the photographic paper P is stored in the loop forming unit 435 (step). S3).
[0058]
  That is, when the leading edge of the photographic paper P reaches the photographic paper sensor S2, the driven roller 438 moves to the drive roller 439 side, and the photographic paper P is sandwiched between the drive roller 438 and the driven roller 439 and fixed at that position. At the same time, the loop guide 436 is moved to the second position (chain line position). In this state, the photographic paper P is continuously pulled out from the magazine 3 by the transport roller 434. As a result, the loop forming unit 435 forms a loop of the photographic paper P. This operation is continued until the loop sensor S1 detects the top of the photographic paper loop.
[0059]
  Next, the photographic paper P having a length necessary for the printing process is sent out from the loop forming unit 435 (step S4). That is, when the driving roller 439 is driven to rotate, the loop forming unit 435 is configured such that the length from the center position of the display surface 414 of the image display unit 411 to the leading end of the photographic paper P is equal to the length necessary for the printing process. The photographic paper P is sent out through the display surface 414 of the image display unit 411. The fed photographic paper P is guided into the photographic paper storage box 461 along the guide plate 462, and is stored in the photographic paper storage box 461 in a loop shape.
[0060]
  Further, a printing process is performed on the photographic paper P (step S5). That is, the pressure pad 416 is pressed against the display surface 414 of the image display unit 411 and the driving roller 439 rotates intermittently in the reverse direction so that the photographic paper P in the photographic paper storage box 461 is displayed on the image display unit 411. The sheet is intermittently reversely fed in close contact with the surface 414. At this time, the image display unit 411 is driven, and images are displayed on the display surface 414 one to several lines in synchronization with the feeding operation of the photographic paper P, whereby the printing process for the photographic paper P is performed. At this time, the photographic paper P in the vicinity of the loop forming unit 435 is returned into the loop forming unit 435 by the reverse feeding of the photographic paper P.
[0061]
  Further, when the printing process is finished, the pressure pad 416 is separated from the display surface 414 of the image display unit 411.
[0062]
  As described above, since the printing paper P is fed back from the stock section 46 and the printing process is performed, an unstable load is not applied to the printing paper P. Therefore, the printing paper P is fed back at a high-precision pitch. It becomes possible.
[0063]
  Further, the printing paper P for which the printing process has been completed is sent out to the cutter unit 47 (step S6). At this time, the driven roller 465 moves to the drive roller 464 side, and the guide plate 462 moves to the chain line position, so that the photographic paper P conveyed from the upstream side is not sent to the photographic paper storage box 461, but the cutter unit 47. Will be conveyed to the side.
[0064]
  In this state, the photographic paper P for which the printing process has been completed is conveyed by the conveying roller 439 to a position where the leading end reaches the photographic paper sensor S3 immediately before the cutter unit 47. At the same time, the photographic paper P is pulled out from the photographic paper reel 33 in the magazine 3 by the transport roller 434 so that the photographic paper P in the loop forming portion 435 is maintained at a substantially constant length. .
[0065]
  In this way, when the leading edge of the photographic paper P reaches the photographic paper sensor S3, the driven roller 465 is pressed against the driving roller 464 via the photographic paper P, and the driving roller 464 is rotationally driven to rotate the photographic paper sensor S3. The length of the photographic printing paper P printed on the basis of this position is conveyed to the cutter unit 47 side. Thereafter, the cutting process of the photographic paper P is performed (step S7). This state is shown in the schematic diagram of FIG.
[0066]
  At the beginning of the cutting process of the photographic paper P, as shown in FIG. 6A, the first cutter 471 and the second cutter 472 are in a separated state, and the guide plate 477 has an inlet 477a on the photographic paper receiving side. In this state, a predetermined length of the printing paper P that has been baked on the basis of the position of the photographic paper sensor S3 is conveyed to the cutter unit 47 side. When a predetermined length of the baked photographic paper P is conveyed to the cutter unit 47 side, the photographic paper P is cut by the first cutter 471 and the second cutter 472 as shown in FIG. .
[0067]
  Further, it is determined whether or not it is necessary to continue the baking process (whether or not the repeat baking is performed) (step S8). Subsequently, when it is necessary to perform the printing process (YES in step S8), it is designated whether or not the printing process has a white edge portion of the photographic paper (whether or not the printing process has a white edge around the printed image). The printing type is determined (step S9). At the time of printing without a white edge (when the border of the image is printed on a wide area by a minute dimension, so-called borderless printing) (NO in step S9), the leading edge of the photographic paper P is cut. (Step S10). That is, as shown in FIG. 6C, the leading end of the photographic paper P after being cut in step S7 is conveyed to the cutter unit 47 side by the driving roller 464 by a predetermined dimension (for example, about 3 mm), and the leading end is Cut by the first cutter 471 and the second cutter 472. As a result, the edge portion of the image that has been printed onto the eye that is wider than the minute dimension (the unnecessary portion on the leading end side of the photographic paper P to be printed next) is cut off. At the time of this cutting, as shown in FIG. 7A, the guide plate 477 located on the downstream side of the first cutter 471 and the second cutter 472 moves to the second position (the chip guide position of the chain line) to generate chips. A is guided into the chip storage box 476. In this way, even if an unnecessary portion of the print edge cut off by the first cutter 471 and the second cutter 472 is scattered at the time of cutting, the receiving port 477a on the transport side is closed, so that it enters the transport side. Thus, no paper jam occurs, and the chips are more reliably guided and stored in the chip storage box 476. Thereafter, the guide plate 477 moves to the original first position (solid-line transport guide position).
[0068]
  Next, it is determined whether or not the length of the photographic paper P to be continuously printed is equal to or less than the distance (for example, 152 mm) between the center of the display surface 414 of the image display unit 411 and the cutter unit 47 (step S11). At this time, the driven roller 465 moves away from the driving roller 464, and the driven roller 438 moves to the driving roller 439 side so that the photographic paper P is sandwiched between the driving roller 439 and the driven roller 438. At the same time, the conveyance roller 436 rotates to form a loop of the photographic paper P in the loop forming unit 435. When the loop sensor S1 detects a loop, the transport roller 436 stops.
[0069]
  Further, when the length of the printing paper P to be printed is equal to or shorter than the above length (YES in step S11), the length between the center of the image display unit 411 and the leading edge of the printing paper P is necessary for the printing processing by the transport roller 439. It will be sent back until it reaches a certain length. At this time, when the length of the photographic paper P required for the printing process is the same as the distance between the center of the display surface 414 of the image display unit 411 and the cutter unit 47, it is not necessary to reversely feed. Thereafter, the pressure pad 416 is brought into pressure contact with the display surface 414 of the image display unit 411, and the printing paper P is intermittently fed back by the conveying roller 439, and the image display unit 411 performs the printing process in the same manner as described above (step S12). ). Thereafter, the process returns to step S6, and the above processing operation is repeated. This state is shown in the schematic diagram of FIG.
[0070]
  In this case, if the distance between the center of the display surface 414 of the image display unit 411 and the cutter unit 47 is set corresponding to the printing size (printing paper size) having a high printing frequency, the second frame less than the printing size is set. During the subsequent printing process, the length required for the printing process of the photographic paper P can be directly fed back from the cutter unit 47 without being stored in the stock unit 46, and the processing speed is increased to increase the printing efficiency. Is possible.
[0071]
  When the length of the photographic paper P necessary for the printing process exceeds the above length (NO in step S11), the pressure is increased until the leading edge of the photographic paper P reaches the upstream position closest to the transport roller 464. The photographic paper P is fed back by the transport roller 439 in a state where the pad 416 is separated from the display surface 414 of the image display unit 411. The photographic paper P is fed out from the loop forming unit 435 and stored in the photographic paper storage box 461 until the photographic paper P reaches a length necessary for the printing process by the transport roller 439.
[0072]
  Further, in a state where the pressure pad 416 is in pressure contact with the display surface 414 of the image display unit 411, the photographic paper P in the photographic paper storage box 461 is intermittently reversely fed by the transport roller 439, and the image display unit as described above. A printing process is performed at 411 (step S13). Then, it returns to step S6 and the said operation | movement is repeated. Note that, in the printing process with a white edge portion (YES in step S9), the processes after step S11 are executed.
[0073]
  When it is not necessary to continue the baking process after the cut process in step S7 (NO in step S8), it is further determined whether or not the printing process has a white edge (step S14). At the time of printing without white edges (NO in step S14), the leading edge of the photographic paper P is cut in the same manner as in step S10 (step S15). Further, at the time of printing processing with a white edge (YES in step S14), the photographic paper P is rewound into the magazine 3 (step S16). The photographic paper P that has been subjected to the printing process is transported to the development processing section 5 by the transport section 48 and is subjected to development processing by the development processing section 5. The photographic paper after the development processing is discharged to the tray 61 of the photographic paper discharge unit 6.
[0074]
  When the leading edge cutting process of the photographic paper P is designated (YES in step S1), the photographic paper drawn from the magazine 3 is loaded onto the transport unit 43 in the same manner as in step S2 (step S17), and then continued. As in step S3, the loop forming unit 435 forms a loop of the photographic paper P (step S18). Further, similarly to step S6, the photographic paper P is conveyed to the cutter unit 47 (step S19), and the leading end is cut at a right angle to the longitudinal direction by a certain length (step S20). Thereafter, the process proceeds to step 11 and a printing process similar to the above is performed.
[0075]
  Next, when the first printing processing unit 2 is selected by the selection key, the magnification is set by the magnification setting key and the start switch is turned on, the film image exposure unit 21 sets the negative film F to 1. Each frame is wound up and a film image is exposed on the printing processing unit 22. On the other hand, the photographic paper P is sequentially pulled out from the photographic paper reel 33 in the magazine 23 a (or 23 b) on the magazine placement unit 24, cut into a predetermined length by the cutter unit 26, and sequentially conveyed onto the printing processing unit 22. Is done.
[0076]
  At this time, drawing of the photographic paper P from the photographic paper reel 33 in the magazine 23 a is performed in synchronization with the winding of the negative film F of the film image exposure unit 21.
[0077]
  Further, the photographic paper printed by the printing processing unit 22 is transported to the downstream side by the transport belt 224, and is transported to the development processing unit 5 side by the horizontal transport unit, the oblique transport unit, the vertical transport unit, and the discharge unit. The photographic paper after the development processing is discharged to the tray 61 of the photographic paper discharge unit 6.
[0078]
  As described above, when borderless printing is performed on photographic paper as a roll-shaped photosensitive material, and then cut to a predetermined size with a cutter, control is performed to cut off the adjacent print edge that has been exposed excessively. Therefore, the adjacent print end portions (end portions of the exposed portions) do not overlap each other and remain unsightly, and there is no margin using the photosensitive material material reel 33 on which the photographic paper P is wound in a roll shape. It can correspond to the printing of the specification. In addition, since the unnecessary portion of the print edge cut off by the cutter unit 47 is guided by the guide plate 477 and stored in the chip storage box 476, the print end cut off by the cutter unit 47 is also provided. Even if unnecessary portions are scattered at the time of cutting, they can be more securely stored in the chip storage box 476. Furthermore, since the guide member drive control unit 479 controls the guide plate 477 to be positioned at the chip guide position into the chip storage box 476 when unnecessary portions of the print edge are cut off, the conveyance guide and the guide guide can be shared. By reducing the number of parts and closing the receiving port 477a at the time of the conveyance guide at the time of the guide guide, it is possible to prevent paper jams that occur when chips are scattered and enter the conveyance system at the time of cutting, and troubles in the processor unit can be prevented. Print time and print loss can be reduced. Moreover, it can pass through a processor part by roller transport by exposing in roll shape at the time of borderless printing, and cutting it into a sheet form before entering a processor part.
[0079]
  In the above-described embodiment, the image display unit 411 of the image transfer unit 41 constituting the second printing processing unit 4 is configured by FOCRT so as to be closely printed, and an image with high definition can be obtained. However, the image display unit 411 can also be configured using a PLZT element instead of the FOCRT. When this PLZT element is used, the drive circuit unit 412 and the image data output unit 413 may be those corresponding to PLZT. The PLZT element in this case refers to a shutter array made of a transparent ferroelectric ceramic material obtained by adding lanthanum to lead zirconate titanate and utilizing the electro-optic effect of the material.
[0080]
  Furthermore, in the above-described embodiment, the length of the photographic paper P conveyed from the loop forming unit 435 to the stock unit 46 during the printing process of the photographic paper in the second printing processing unit 4 is as long as necessary for the printing process. However, it is also possible to carry it a little longer than that. In addition, it goes without saying that various modifications can be made to the detailed configuration and operation of the printing and developing processing apparatus in the above-described embodiment.
[0081]
【The invention's effect】
  As described above, according to the first aspect of the present invention, in the case of printing with a margin, the printed photosensitive material is cut into a predetermined length by the cutter member, and the printing of the marginless specification is performed. In some cases, the photosensitive material is cut to a predetermined length, and further, the adjacent print end (exposed portion end) is controlled so as to cut off the end portion of the adjacent print that has been exposed excessively. Prints with no border (borderless) specifications that are cut off after successive close-baking processes using a photosensitive material reel in which the photosensitive material is wound in a roll. Can also respond.
[0082]
  Further, when the photosensitive material is cut to a predetermined length, the second guide member is positioned at the conveyance guide position, and when the unnecessary portion of the print end is cut off, the second guide member is positioned at the chip guide position. Therefore, the conveyance guide and guide guide can be shared, reducing the number of parts, and even if unnecessary parts of the print edge cut off by the cutter member are scattered during cutting, they are more securely stored in the chip storage member. As a result, it is possible to prevent chips from being scattered and entering the conveying system when clogging.
